> Currently DML apply updates in batches equal to {{SqlFieldsQuery.pageSize}}. 
> This is prone to deadlocks. Instead, we should apply updates one-by-one by 
> default. Proposal:
> # Introduce {{SqlFieldsQuery.updateBatchSize}} property, set it to {{1}} by 
> default
> # Print a warning about deadlock to log if it is greater than 1
> # Add it to JDBC and ODBC drivers
> # Add it to other languages
